FIELD OF THE INVENTION

The invention generally relates to a system and method to determine location information of a portable computing device and, in particular, to a secure and scalable system and method of decoupling and exposing handset originated location information to third parties.

BACKGROUND

Faced with an increasingly difficult challenge in growing both average revenue per user (ARPU) and numbers of subscribers, wireless carriers are trying to develop a host of new products, services, and business models based on data services. One such service is location services, which provide information specific to a location. It is expected that location based services will generate additional business for the carrier, from both the mobile user and content providers.

For the mobile user as well as the service provider (wireless carriers and content provider), location-based services offer many opportunities. For example, location-based services can increase revenue of the service provider, e.g., network carrier and content provider, while improving services to end users, e.g., mobile users. Some examples of location-based services that can be provided to the mobile user include:

-   -   Providing the nearest business or service, such as an ATM or         restaurant;     -   Providing alerts, such as notification of a sale on gas or         warning of a traffic jam; and     -   Providing weather reports which are germane to the location         where the user is currently located, etc.

For the network carrier, location-based services provide value add by enabling services such as:

-   -   Resource tracking with dynamic distribution (e.g., Taxis,         service people, rental equipment, doctors, fleet scheduling);     -   Finding people or information for the user (e.g., person by         skill (doctor), business directory, navigation, weather,         traffic, room schedules, stolen phone, emergency 911);     -   Proximity-based notification (push or pull) (e.g., targeted         advertising, buddy list, common profile matching (dating),         automatic airport check-in); and     -   Proximity-based actuation (push or pull) (e.g., payment based         upon proximity.

While the potential of these services is obviously great, and there is a considerable amount of interest with respect to these services, there are a number of issues that have to date limited the actual rollout and deployment of these services. These issues include for example,

-   -   Wireless service providers have not yet determined the         appropriate authorization model around these services, in order         to protect consumer privacy and conform to a rapidly evolving         regulatory environment;     -   There are challenges being faced by the wireless service         provider community with respect to the actual revenue generating         services to roll out and the priority with which this should         happen;     -   External content providers who hold the keys to content are         hesitant to allow service providers access to top tier content         (e.g., movies and music, etc.), preferring to maintain their         existing relationships with their subscribers; and     -   Location platforms (i.e., network carrier equipment used to         pinpoint location of user) which are centrally housed in carrier         networks (especially in current 3G networks) have known issues         with respect to throughput, latency, in terms of actual location         transactions, etc. Also, cell sector dips (manner in which to         determine user locations (either coarse or fine granularity))         are expensive, with precise fixes even more resource expensive.

In addition, for purposes of location based services, external content providers typically request location from the carrier domain on a transactional basis. For example, a weather service content provider would typically request location information pertaining to a subscriber as soon as a request was received from the handset, resulting in addition latency received by this request from a subscriber perspective. It is also known that the process for a third party to gain access to a carrier's location platform is a long and expensive process because the third party has to build the integration infrastructure and the carrier must set up their location platform to accept and throttle the requests. There is also a certification and shakeout period, which can be an expensive and slow process.

Accordingly, there exists a need in the art to overcome the deficiencies and limitations described hereinabove.

DETAILED DESCRIPTION

The invention generally relates to a system and method to determine location information of a computing device. In particular, the present invention provides a secure and scalable system and method of decoupling and exposing handset originated location information to third parties in order to obtain location specific content from a content provider. Advantageously, the invention simplifies the location retrieval for third party content providers while continuing to offer location as a revenue generating service for service providers (network carriers).

As content providers are working at a frantic pace to make their content more mobile friendly, the present invention will allow the service providers to cater to handset based consumers without the need for content providers to build a new infrastructure for the dissemination of their content. Also, the present invention improves the operational efficiency associated with realizing location sharing between network carriers and trusted third parties (content providers) for the purpose of providing location information to the content provider which, in turn, can provide location specific content (e.g., weather report) to the user (handheld device). By using the system and method, the user no longer has to manually specify ZIP codes or other location identifiers to use location based services, when they roam into a different location.

In implementation, the present invention provides a mechanism of securely providing the location information to the trusted third party without any major modifications to the existing infrastructure of the network carrier. (This is compared to current systems in which adapting a web site to obtain location information means that an existing content provider has to implement major infrastructure changes to accommodate location (e.g., integrate with the carrier infrastructure)). Thus, the present invention allows for the reuse of the existing OTA (Over the Air) provisioning infrastructure that network carriers have invested significant dollars in already, with minimum adaptation to support handset agents on MIDP and non-MIDP compliant handheld devices. The present invention also allows for network carriers to share location information with partners without compromising privacy, which is an issue facing the commercialization of location based services. Also, this invention provides the network carriers viable means of protecting their investments and a path to realize better ARPU (Average Revenue per Unit) from location based services in view of devices with A-GPS chipsets which can send location information directly to third parties and thus bypass the carrier pipe.

The present invention also relies on the existence of a basic authorization model and assumes that subscribers, service providers (e.g., network carriers) and content providers have opted into the appropriate services (e.g., location based services) and subsequent sub-services (e.g., location based weather services). In embodiments, the present invention can be implemented in numerous ways in order to obtain content from a content provider based on location information. These methods can include, for example, detecting location resident in header information of an HTTP request sent by the handheld device, securely bundling the location information, service subscription information and content request in the HTTP header with an authorization key and providing such information to an appropriate content provider. The content provider can then use the location information to provide the appropriate location specific content to the requesting party, without the need for building the integration infrastructure, setting up their own location platform to accept and throttle the requests, or requesting certification and shakeout period from the network carrier.

In embodiments, the location information can be obtained by an agent sitting locally on the handheld device (also referred to as a handset, PDA, mobile computing device, etc.), at a service provider or network carrier infrastructure. The agent can be used to determine location information using many different methodologies. By way of one example, a local agent residing on the handheld device can use locally cached location information obtained by GPS, A-GPS or mechanisms other than the telecommunications network in order to determine location information. In other embodiments, the agent can obtain information from control plane locating, e.g., the service provider (e.g., network carrier) obtains the location based on the signal-strength of the closest cell-phone towers. The system of the invention requires no reverse tunneling or reverse proxying infrastructure.

The signal provided to the carrier may be, for example, a wireless application protocol (WAP). Those of skill should recognize that WAP enables access to the Internet from a handheld device. For example, a WAP browser provides all of the basic services of a computer based web browser but simplified to operate within the restrictions of the handheld device. Those of skill in the art should also appreciate that the present invention is not limited to WAP applications, but may be implemented using any wireless data protocol such as, for example, the Japanese i-mode system.

Exemplary System Environment and Infrastructure

FIG. 1 shows a general schematic overview of the present invention. Specifically, in implementation, a handheld device 100 will send an HTTP request to a content provider 300 over a network carrier (infrastructure) 200. In use, each HTTP request travels across the infrastructure of the network carrier 200 before being routed through the Internet to the content provider 300 (destination site). Before leaving the infrastructure of the network carrier 200, a unique scrambled (encrypted) component containing the user's location information is added to the HTTP request. An authorizing key may also be sent to the content provider in order to gain authorization to the location information.

The location information may be obtained directly from the location platform (on the network carrier infrastructure 200) or, optionally, on an agent residing locally on the handheld device 100. In either scenario, the location platform or local agent intercepts the HTTP stream and inserts the location information into the header of the HTTP request. The user's location information can contain different levels of precision such as:

-   -   Coarse location (cell sector) along with a timestamp associated         with when the fix was made;     -   Precise location along with a timestamp associated with when the         fix was made; or     -   A data structure that contains both coarse and fine location.

The content provider 300 can access the HTTP request and in particular the user's location information by many different methodologies. For example, the network carrier 200 can provide the content provider 300 with a decryption key that expires in a set amount of time and/or after a predetermine limit of uses. Alternatively, the network carrier 300 (or service provider) can provide a network carrier hosted decryption service (API) that accepts the encrypted location data from the user's HTTP request (and/or ID of the content provider 300 and/or handheld device 100). In this latter scenario, the network carrier hosted decryption service would return the unencrypted user's location to the content provider 300. The network carrier 200 hosted decryption service can also enforce a limited number of decryption requests per time period, etc. The API call back to the network carrier 200 is significantly less intensive than the currently available location call.

In embodiments, a charging model can be implemented to increase revenue of both the network carrier 200 and the content provider 300. For example, the network carrier 200 can charge the content provider 300 for the location information services on a per request basis, type and/or amount of requested content, etc. Additionally, the network carrier 200 can charge differently for decrypting coarse location versus fine location or based on a subscription and/or other fee agreement. On the other hand, the content provider 300 can charge the end user (handheld device 100) for specific content, on a per request fee, on a subscription basis or other charging scheme.

FIG. 2 shows an illustrative environment 10 for managing the processes in accordance with the invention. To this extent, the environment 10 includes a server 12 that can perform the processes described herein. In particular, the server 12 includes a computing device 14, which can be resident on an infrastructure of a network carrier, a content provider server, or other third party service provider (any of which is generally represented as reference numeral 200 in FIG. 1).

The computing device 14 includes a Management Tool (Agent) 14 a configured to make computing device 14 operable to perform the services described herein. The implementation of the Management Tool 14 a will provide a speedy and efficient way in which partners (e.g., content providers and network carriers) are boarded onto location platforms within the carrier network. By way of illustration, the Management Tool 14 a can intercept the HTTP request, determine location and service subscription information of the user, encrypt such information and send it to the content provider, without the need for any major infrastructure overhaul by either the network carrier or content provider.

More specifically, in one implementation, the Management Tool 14 a determines a location of the handheld device using control plane locating methodologies. The Management Tool 14 a can also be provided with the location information from a local agent residing on the handheld device. For example, the local agent can obtain location information by GPS, A-GPS or mechanisms other than the telecommunications network. The Management Tool 14 a can also determine whether the user is entitled to certain services/content by using, for example, a simple look-up table that matches the ID of the handheld device to available content/services. This look-up table can also be resident on a server at the content provider, and periodically updated by the service provider.

As this information is obtained, the Management Tool 14 a can insert an authorizing key (e.g., via encryption) into the header of the HTTP request which, in turn, is forwarded to a specific content provider. The authorizing key may be obtained based on many different charging models as described herein. The authorizing key ensures secure transmission of the deliver location information to a content provider and, in embodiments, provides authorization to use the location information for location specific content dissemination. The content provider can open the HTTP request, decrypt the information (or request the content provider to decrypt the information), read the information, (e.g., location information, requested content, etc.) and provide the requested location-based content to the user through the carrier infrastructure.

In embodiments different charging models are contemplated by the present invention. For example, the service provider or network carrier can charge the content provider on a per request basis, bulk basis or flat rate model for the end user location information. A fee can also be based on the type of location information provided to the content provider, e.g., fine or coarse location. Any of these models will be less expensive than the expenditures needed to build and maintain a standalone infrastructure for such services. In return, the content providers can generate revenue from the end user by charging a flat fee, per use charge, etc. for the location based content.

The computing device 14 also includes a processor 20, the memory 22A, an I/O interface 24, and a bus 26. The memory 22A can include local memory employed during actual execution of program code, bulk storage, and cache memories which provide temporary storage of at least some program code in order to reduce the number of times code must be retrieved from bulk storage during execution. In addition, the computing device includes random access memory (RAM), a read-only memory (ROM), and a CPU.

The computing device 14 is in communication with the external I/O device/resource 28 and the storage system 22B. For example, the I/O device 28 can comprise any device that enables an individual to interact with the computing device 14 or any device that enables the computing device 14 to communicate with one or more other computing devices using any type of communications link. The external I/O device/resource 28 may be for example, the handheld device.

In general, the processor 20 executes computer program code, which is stored in the memory 22A and/or storage system 22B. While executing computer program code, the processor 20 can read and/or write data to/from memory 22A, storage system 22B, and/or I/O interface 24. The program code executes the processes of the invention. The bus 26 provides a communications link between each of the components in the computing device 14.

The computing device 14 can comprise any general purpose computing article of manufacture capable of executing computer program code installed thereon (e.g., a personal computer, server, handheld device, etc.). However, it is understood that the computing device 14 is only representative of various possible equivalent-computing devices that may perform the processes described herein. To this extent, in embodiments, the functionality provided by the computing device 14 can be implemented by a computing article of manufacture that includes any combination of general and/or specific purpose hardware and/or computer program code. In each embodiment, the program code and hardware can be created using standard programming and engineering techniques, respectively.

Similarly, the server 12 is only illustrative of various types of computer infrastructures for implementing the invention. For example, in embodiments, the server 12 comprises two or more computing devices (e.g., a server cluster) that communicate over any type of communications link, such as a network, a shared memory, or the like, to perform the process described herein. Further, while performing the processes described herein, one or more computing devices on the server 12 can communicate with one or more other computing devices external to the server 12 using any type of communications link. The communications link can comprise any combination of wired and/or wireless links; any combination of one or more types of networks (e.g., the Internet, a wide area network, a local area network, a virtual private network, etc.); and/or utilize any combination of transmission techniques and protocols.

In embodiments, the invention provides a business method that performs the steps of the invention on a subscription, advertising, and/or fee basis. That is, a service provider, such as a Solution Integrator, could offer to perform the processes described herein. In this case, the service provider can create, maintain, deploy, support, etc., the computer infrastructure that performs the process steps of the invention for one or more customers. In return, the service provider can receive payment from the customer(s) under a subscription and/or fee agreement and/or the service provider can receive payment from the sale of advertising content to one or more third parties.

Exemplary Processes

FIG. 3 is a flow chart implementing steps of the invention, which may be implemented in the environment of FIGS. 1 and 2. FIG. 3 may equally represent a high-level block diagram of the invention. The steps of FIG. 3 may be implemented and executed from either a server, in a client server relationship, or they may run on a user workstation (which can be generally represented in FIGS. 1 and 2). Additionally, the invention can take the form of an entirely hardware embodiment, an entirely software embodiment or an embodiment containing both hardware and software elements. Software includes but is not limited to firmware, resident software, microcode, etc. Furthermore, the invention can take the form of a computer program product accessible from a computer-usable or computer-readable medium providing program code for use by or in connection with a computer or any instruction execution system. The software and/or computer program product can be implemented in the environment of FIGS. 1 and 2. For the purposes of this description, a computer-usable or computer readable medium can be any apparatus that can contain, store, communicate, propagate, or transport the program for use by or in connection with the instruction execution system, apparatus, or device. The medium can be an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system (or apparatus or device) or a propagation medium. Examples of a computer-readable medium include a semiconductor or solid state memory, magnetic tape, a removable computer diskette, a random access memory (RAM), a read-only memory (ROM), a rigid magnetic disk and an optical disk. Current examples of optical disks include compact disk-read only memory (CD-ROM), compact disk-read/write (CD-R/W) and DVD.

FIG. 3 illustrates an exemplary process in which the service provider and content provider initiate and establish a relationship in accordance with the invention. In particular, at step S100, the content provider and service provider initiate an attempt to establish a relationship by which location exposure is enabled. In embodiments, at step S100, the content provider requests this service from the service provider, e.g., network carrier or third party service provider.

At step A200, the service provider and content provider decide the type of service that is required. For example, at step S200, a determination is made as to whether coarse or fine location (or both) is required and which content will be available to an end user, based on location information.

At step S300, a charging model will be established between the service provider and the content provider. The charging model may be, for example, a requirement that accounting records from the participating nodes in the call flow be sent into the carrier platform, a flat fee based service or a fee based on coarse or fine location information or a host of other usage options as discussed herein and equivalents thereof. After this, the actual deployment model is finalized. This could result in several scenario models as discussed in more detail below. For example, at step S400, the carrier network may determine whether the end user is entitled to such services, in which case the carrier network will issue the credentials (authorizing key) to the content provider. The carrier network will also determine whether location information was obtained locally at the handheld device.

If the location information was not obtained locally at the handheld device, the process continues to the third party content provider. That is, at this phase, the location information (obtained by the location platform) and the credentials are securely sent to the third party content provider. The third party content provider can then decrypt the location information via the methodologies discussed herein. The requested location sensitive content can then be sent back to the end user.

If the location information was obtained locally at the handheld device, the process continues to S500. At step S500, the network carrier will update the network routing proxy. More specifically, at step S500, the network carrier establishes a routing model which may include, for example, a look-up table (e.g., stored in the storage 22B) which stores routing information, matching information between the end user and content provider, user ID information, etc. In embodiments, the network carrier and/or service provider can white-list sites where location information can be sent and blacklist sites where location information cannot be sent. The proxy is also configured to scramble (encrypt) a tag (location information) in the HTTP header of the request, such that the location information in the HTTP request can be securely transmitted to the content provider.

Regardless of the proxy in the carrier domain, decryption can be local to the content provider or hosted as a service exposed by the service provider. As such, at step S600, a determination is made as to whether the decryption will be managed locally (at the network carrier or content provider). If the decryption is to be handled locally, at step S700, the message is decrypted. The process will continue to the content provider, which will provide the location specific content. If the decryption is not to be handled locally, the process will continue to the content provider, which will decrypt the location information, amongst other possible encrypted data.

Exemplary Embodiments

FIGS. 4 and 5 show alternative embodiments implementing aspects of the invention. FIGS. 4 and 5 may equally represent high-level flow diagrams implementing processes in accordance with aspects of the invention. Both FIGS. 4 and 5 show a handheld device 100, a carrier network 200 and a content provider 300. The carrier network 200 includes an encryption service, location platform, decrypting service and charging platform (all of which was generally referred to as the Management Tool 14 a), which is described in more detail below.

More specifically, as shown in FIG. 4, the handheld device 100 sends an HTTP request to the content provider 300. The carrier network 200 intercepts the HTTP request and inserts scrambled location information into the request, either obtained from a location platform or from the device itself. In FIG. 4, the scrambled location information is provided by the encryption service (proxy). In the contemplated embodiment of FIG. 4, the location platform provides the location information (although in other embodiments, the location platform can receive the cached location information from the handheld device). The carrier infrastructure 200 sends the encrypted information (location information, user ID, etc.) to the content provider 300, which decrypts the location information with a decryption key obtained from the network carrier 200 or service provider. The decryption key allows the content provider 300 to identify the handheld device, look for the key and unscramble the embedded location information in the header of the HTTP request.

Alternatively, the network carrier 200 (or other service provider) can provide decryption services using, for example, a decryption service as discussed above (also referred to as a decryption agent). The decryption service allows the content provider 300 to decrypt location information from the HTTP header request. The network carrier 200 (or service provider) can provide the optional local decryption service negotiated before hand as part of the provisioning flow. Thus, the decryption agent (e.g., decryption service) allows the network carrier 200 to identify the handheld device, look for the key and unscramble the embedded location information in the header of the HTTP request for the content provider.

The network carrier infrastructure 200 also includes a charging platform which is configured to receive accounting information from all the participants in the runtime call flow. For example, all runtime infrastructures can be optionally connected to the charging platform in the service provider domain so as to facilitate the accounting and subsequent charging and revenue settlement processes. As a further contemplated embodiment, transaction detail records (TDR) can be provided to the charging platform from components of the infrastructure of the network carrier 200 to facilitate the accounting and subsequent charging and revenue settlement processes. The TDR can include, for example, the length and time of the transmission, the requested content, the amount of content acquired, or other information necessary to calculate a fee to charge to the content provider.

In FIG. 5, the handheld device 100 includes a local agent which caches location information from a standard Assisted GPS (A-GPS) chipset local to the handheld device 100. The local agent also has the ability to intercept HTTP traffic emanating from the browser of the handheld device in a configurable manner such that location information can be provided to the network carrier 200. Much like the embodiment of FIG. 4, the network carrier 200 can then encrypt the location information and provide such encrypted information to the content provider 300. In embodiments, the network carrier and/or handheld device and/or service provider can white-lists sites where location can be sent and blacklists sites where location cannot be sent.

In this implementation, the network carrier 200 (service provider) includes the location platform. The network carrier 200 (service provider) can also include the charging platform as discussed above. Also, in this implementation, the decryption is provided by the content provider 300; although, it is contemplated by the present invention that the network carrier 200 (service provider) can include decryption services. Also, the TDR can be provided to the carrier 200 from the remaining participants, 100, 300.

Illustrative Examples

By way of an example, a free weather web site utilizes advertisement as a main source of revenue. This site wants to test the impact of location based services and advertisement, but by implementing the invention it no longer has to go through the expensive and complex process of integrating with a carrier's location platform. Instead, the weather website simply acquires a trial decryption key or a trial client ID from the network carrier for a limited amount of time. After making minimal changes to their web application to access the user's location from the HTTP request, the site no longer has to prompt the user for their location. Additionally, the advertisements on the web site are now targeted based on the user's location. In this way, the weather website experiences increased user traffic because their website can offer immediate local weather on the first page. The weather website also experiences an increase in advertisement clicks because they are more relevant to the user. The weather website considers this a successful trial of location based services and signs up for a more permanent plan with the network carrier to continue their access to a location decryption method.

In use, a subscriber turns on his/her mobile browser on his handheld device and goes to a weather site. The handset housed agent (or the proxy agent on the carrier network) intercepts the HTTP stream and adds a scrambled location tag to the header. The weather site receives the request and as a result of its arrangement with the network carrier, has the key to descramble the tag in the HTTP header. The weather site can now determine the subscriber coarse or fine (cell sector) location and provide location sensitive weather information to the subscriber. The subscriber can now plan his/her activities based on the location specific weather report.
